Brighthouse Daytona HD Picture Quality

[hale]

I currently Viewed HD programming over a relative's house on a 1080i viso 42 Inch TV. I Thought the HD programming specifically WWE Raw Live, didn't seem that much better than Standard programming on the same box. This was a Brighthouse box not Tivo. Hooked up HDMI myself. I have seen blueray even though it can't compare to TV source.

Any thoughts on other people views on the picture quality?

Thanks
